HANDLEY, OF GLENDALE, NEWYORK, ASSIGNOR 'I'O ROYAL TYPEWRITER COMPANY, INC., OF NEW YORK, N. Y.,A CORPORATION OF NEW YORK 'IYPEWRITING- MACHINE Application filedDecember 11, 1928. Serial No. 325,320.

This invention relates generally to improvements in typewritingmachines, but more specifically to a billing device employed inconnection with and forming a part of a typewriting machine.

In billing operations generally, it is de sirable to typewriteindividual invoices and simultaneously record the typewritten data on asales journal or book sheet. The book sheet is first placed around theplaten and then the first invoice and intermediate carbon are placedaround the platen in front of the book sheet. The account data is thenprinted simultaneously on the invoice and on the book sheet, and theinvoice and carbon are then removed from the machine. The operator theneffects a line spacing operation to the book sheet, another invoice andcarbon are then inserted, and the new data is then printedsimultaneously on the invoice and book sheet. Heretofore it has beenusual to turn the platen backwardly, together with the record sheet andcarbon to receive the new invoice, and then to turn the platen forwardlyinto its position for writing the first line upon the invoice.

The principal object of the present invention is to provide meansincluding a manu ally operable lever which during movement of the leverwill successively efiect a line spacing operation and a release of saidpressure rolls whereby the book sheet will be line spaced and thepressure rolls will be immediately thereafter released to permit theready withdrawal of the printed invoice and carbon and the readyinsertion of a new invoice and carbon, the return movement of theoperating lever eiiecting the return of the pressure rolls to operativeposition, without however effecting the line spacing mechanism.

A further object of the invention lies in the provision of a secondmanually operable lever for releasing the pressure rolls only andmovable entirely independent of the lever which effects the successiveline spacing operation and the release of the pressure rolls, thuspermitting the invoice to be adjusted properly with respect to the booksheet.

In the accompanying drawings, there is illustrated a portion of a Royaltypewriting machine, although if any other typewriter may be employed ifdesired.

The machine includes a carriage A having end plates 5 and a platen Bhaving axles 6 which are respectively journaled in said end plates. Thecarriage includes on its left side the usual line spacing means (notshown) which is employed where the usual single line spacing is requiredbetween separate items on invoices. Such line spacing means may beconstructed in accordance with the Hess & Myers Patent 1,127,468. Aug.29, 1922.

Front pressure rolls 7. which are in the form of sleeves. are looselytitted on a rod 8 extending parallel with the platen. Obviously one ormore rolls 7 may be employed as desired. The rod 8 is supported on theforwardly extending arms 9 of hell crank levers 10 which are pivoted attheir angles as at 11 to the carriage A. The rearwardly extending arms12 respectively engage in cam grooves 13 which extend transversely of anoscillating or rock shaft 14 and bear against the respective bottom oreccentric surfaces 15 formed by said grooves, as shown in Figure 4. Coilsprings 16 are each connected at one end as at 17 to the forwardlyextending arm 9 of the bell crank lever 10, and at its other end to apin 18 fixed to the carriage A. These springs function to normally andyieldably retain the front pressure roll 7 in contact with the platen.Upon oscillation of the rock shaft 14 in one direction, the cam surfaces15 will oscillate the bell crank levers 10 against the tension of thesprings 16 and thereby release or separate the front pressure rolls fromthe platen.

A. rear pressure roll 19 has its ends journaled in lever arms 20, oneonly being shown, which have their rear ends pivoted as at 21 to thecarriage A. The free ends of the arms 20 are each engaged in a camgroove which extends transversely of the rock shaft 14, and bearsagainst the bottom or eccentric surface 22 formed by said groove, asshown in Figure 4. A flat spring 23 is connected at one end to thecarriage A and has its free end bearing on the arm 20 to normally andyieldably retain the rear pressure roll 19 in contact with the platen.On oscillation of the rock shaft 14 in one direction, the cam surfaces22 will swing the lever arm 20 against the tension of the spring 23 andthereby release or separate the rear pressure roll from the platen.

In order to actuate the rock shaft 14, I have pivoted a manuallyoperable lever 24 on a stud screw 25 mounted on the right hand end plate5 of the carriage. This lever is provided with an arcuate rack 26 whichengages a gear 27 fixed to the rock shaft 14. Thus upon a forward pullon the lever 24 by the operator, the rock shaft 14 will be oscillated ina direction to release simultaneously the pressure rolls 7 and 19 fromcontact with the platen, and upon release of said lever by the operator,the springs 16 and 23 will automatically return all of the parts totheir initial positions.

In order to effect a line spacing operation of the platen andsimultaneously release the pressure rolls 7 and 19 from contact with theplaten, I have provided the following mechanism The axle 6 on the righthand end of the earriage, projects beyond the end plate 5 and a bracket28 is loosely mounted on the projecting portion of the axle 6. Thisbracket includes a plate 29 and upper and lower plates 30 and 31respectively, the plates 30 and 31 being disposed in the same verticalplane and being united with the plate 29 through the medium of aconnecting portion 32, the bracket 28 being held against rotary movementwhen the platen is turned, by means of a rod 33 whiehconnects the endplate 5 and the plate 29 of said bracket. A combined line spacing andpressure roll releasing lever 34 is pivotally mounted on the axle 6adjacent the plates 30 and 31 of the bracket 28. Also journaled .A

on the axle 6 is a pawl or supporting arm 35, and to the outer end ofthis arm is pivotally connected as at 36 one end of a pawl 37 adapted toengage a ratchet wheel 38 fixed to the axle 6 of the platen. A coilspring 39 has one end connected to the pawl 37 and the other endconnected to the arm 35 for yieldably urging the pawl into engagementwith the ratchet wheel 38. A stop, 40. as shown in Figures 1 and 5,extends laterally from the front edge of the plate 29 of the bracket 28and serves to limit the downward movement of the arm 35. A latch 41' ispivotally connected intermediate it-s ends as at 42 to the lever 34. Oneend of the latch 41 provided in its under surface with a cutout forminga resultant shoulder 44. The cutout 43 is normally adapted to embrace apin 45 which is angular in cross-section and extends laterally from thepawl supporting arm 35, the shoulder 44 cooperating with the pin tonormally connect the arm 35 with the lever 34. A coil spring 46 isconnected at one end to a pin 47 fixed to the lever 34 and at its otherend to a pin 48 fixed to the end of the latch 41 at a point adjacent theshoulder 44. This spring 46 functions to yieldably retain the latch inengagement with the pin 45. It will be observed that as long as thelatch 41 is connected with the pin 45, the pawl 37 will be movedrearwardly with the lever 34 in order to bring about a line spacingoperation to the platen. After the platen has been rotated apredetermined distance so as to effect a line spacing movement, it isdesirable to disconnect the latch from the line spacing mechanism so asto permit the lever 34 during its continued movement in the samedirection to effect a release of the pressure rolls 7 and 19. To thisend, I have provided the plate 30 of the bracket 28 with a pin 49against which the nose 50 of the pawl 41 will engage and thereby swingsaid pawl upon its pivot 42 and release the shoulder 44 from the pin 45,thereby disconnecting said latch from the line spacing means.

It is desirable to provide means for varying the extent of movementimparted to the platen during the line spacing operation so as to permitone or more line spacings as may be desired. For this purpose. I haveprovided a shield 51 for the pawl 37. This shield 51 is provided with asupporting flange having an arcuate slot 53 formed therein. Screws 54extend through the slot and engage threaded openings in the plate 29 ofthe bracket 28. By means of this pin and slot connection between thebracket and the shield, the latter may be adjusted relative to the pawland thereby vary the time when the pawl 37 en gages the ratchet wheel38. The earlier the pawl engages the ratchet wheel the greater will bethe line spacing movement imparted to the platen, and vice versa, thelater the pawl engages the ratchet wheel the lesser the movement. Theflange 52 is formed on its lower edge with a series of ratchet teeth 55which are engageable with a retaining pawl 56 pivoted on the plate 29 asat 57 and yieldably held in engagement with the teeth by a spring 58.

In order to effect a release of the pressure rolls 7 and 19 immediatelyfollowing the line spacing operation and during the latter part of themovement of the lever 34 in one direction, I have provided thelower endof said lever with an arcuate cutout 59 which is arranged concentricallywith the axis of said lever, and forms resultant spaced stop shoulders60 and 61. Fixedly connected to the gear 27 is a laterally extending arm62, said arm extending to the right as viewed in Figure 1, and having arigid gear 63, similar to the gear 27, fixed thereto, the gear 63 beingpivotally supported on the plate 31 through the medium of the pivot pin64. A gear 65, as shown particularly in Figure 10, is pivoted on a screw66 carried by the plate 31 of the bracket 28. This gear 65 is normallyin mesh with the gear 63, and is provided with a projection or finger 67which is located within the cutout 59 of the lever 34. Thus uponoscillation of the lever 34, the shoulders 60 and 61 will alternatelyengage the projection 67 and thereby oscillate the gear 65 which in turnwill oscillate the gear 63, the arm 62, the gear 27, and consequentlythe rock shaft 14:. Thus the lever 34 in its forward direction ofmovement will release the pressure rolls 7 and 19, and in the oppositedirection of move ment will permit said rolls to return to their platenengaging position. The shoulders 60 and 61 are spaced apart a distanceso that upon the rear movement of the lever 3% the shoulder 61 will notengage the projection 67 until after the latch 41 has been released fromthe line spacing mechanism and consequently the pressure rolls 7 and 19will be released only after the completion of the line spacingoperation.

Rolls 68 are rotatably mounted on a graduated rod 69 which is secured atits ends to the swinging bail arms 70. These rolls are also supported onthe rod for independent adj ustment therealong. The arms 70 are pivotedas at 71 to the end plates 5 of the carriage A. A coil spring 72 whichis connected at one end to each bail arm 70 and at its other end to theend plate of the carriage, functions to yieldably retain the rolls 68against the platen B. These rolls 68 are the means for holding thejournal or book sheet 0 in position when the other two sets of feedrolls 7 and 19 are released for the insertion and removal of theinvoices, thus permitting the retention of the book sheet in the linespace position where the last entry was made subsequent to the rotationof the platen and feed rolls preparatory to removing the invoices.

In operation the lever 24 is first moved forwardly to release thepressure rolls 7 and 19 from the platen. The journal or book sheet 0 isthen inserted around the platen between the platen, and the separatingplate 73 and the pressure rolls 7,19 and 68. An invoice or billhead Eand carbon sheet D are then inserted between the separating plate 73 andthe table or support 74. and between the hook sheet C and the pressurerolls 7, 19 and in front of the rolls 68. The lever 21 is then releasedby the operator and this lever together with the pressure rolls 7 and19, then return to their initial positions. The desired entries are thenprinted on the invoice E and simultaneously on the record or book sheetC. The lever 34: is then moved rearwardly to first efifect a linespacing operation to the book sheet C and to subsequently effect arelease of the pressure rolls 7 and 19 during the continued rearwardmovement of said lever. The printed invoice E together with the carbon Dare then removed, a new invoice and carbon are then inserted and thelever 3% moved forwardly to its initial position. This operation isrepeated as often as desired and as a result the line spacing operationafter each invoice is completed, the entries on the book sheet arespaced uniformly apart.

I claim:
